Yeah, it's a good point, the law that may result from parliament does need to be clear on where the line is drawn.

Personally, I would expect singleplayer and LAN to work at EOL

Edit: on 3rd party libraries & services, I would expect that such vendors would need to make their software compliant for their customers after any law change on this front. No one is gonna buy GameLift if it's a legal liability for their EOL plan
